SPECIFICATION forming part of Letters Patent No. 612,035, dated October11, 1898.

Application filed September 7, 1897. Serial No. 650,765- (No model.)

To all whom it may concern:

Be it known that I, PAUL 1V. HAMMERLE, a citizen of the UnitedStates,residing at I-Iastings, in the county of Dakota and State ofMinnesota, have invented certain new and useful Improvements inInsect-Exterminators; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in devices for exterminatinginsects and which works on the principle of an atomizer, which by meansof a current of air throws a fine spray of water containing dissolvedparisgreen or other poison. Heretofore as far as said principle has beenapplied for similar purposes the atomizers have been made of so small,unhandy, and unfit construction that they have about amounted to a smallsyringe, which the farmer, for instance, using it for the exterminationof potato-bugs, must squirt several times on a single stand or plant ofpotatoes, and to make the process still slower the apparatus is inactivehalf the time, while the operator retracts the plunger.

The objects of my invention are, first, to provide aninsect-exterminator on the atomizing principle, but throwing a large andcontinuous spray; second, to so construct said machine that it may besecured on a persons body and operated by both hands, and, third, tomake the operating-crank of such machine extensible and reversible toeither side of the machine, so that it may be operated by either handand by a strong or weak person. These and other objects I attain by thenovel construction and arrangement of parts illustrated inthe'accompanying drawings, in which Figure 1 is a front elevation of mycomplete machine mounted or secured upon the operator and in operation.Fig. 2 is a side View of the apparatus detached from the operator. Fig.3 is a central vertical section through the air-cylinder of theapparatus. Fig. '4 is a top view, and Fig. 5 a side View, of theatomizin g parts of the apparatus. Fig. 6 is an enlarged detail View ofthe crank mechanism of the device.

Referring to the various parts in the drawings by reference-numerals, 1represents the person operating the machine. Upon him are secured, bythe shoulder-straps 2 and the side bands 3, the back board or plate 4and the front board or plate 5, uponwhich are secured theforwardly-extending arms 6, to the front ends of which is secured adouble acting air-pump, consisting of the air-cylinder 7 and the piston8 moving therein, and having the piston-rod 9, which is secured in themiddle of the cross-head 10, from the ends of which 6X tend the twopitmen 11, which have their lower ends operated by the cranks 12, formedone at each end of the shaft 13, journaled in the bearings 14, providedat the lower end of the cylinder.

As best shown in Fig. 6, the cranks 12, after being extended through thepitmen 11, which are retained thereon by the pins 15 or other suitablemeans, have their ends 16 made four-cornered, so as to fit in fourdifferent positions in the square hole of the hand-crank 17, which isdetachablysecured on the end 16 by means of the spring-dog 18, securedat 19 to the crank, and, projecting through the aperture 20, engages,one at a time, the notches 21 in the corners of the crank portion 16.Thus the operator may at any time take hold of the toe 22 of thespring-dog 18 and by raising it slightly remove the crank 17 and replaceit in either of the positions indicated (three of them in dotted lines)in Fig. 2, thereby varying the leverage or distance from the center ofthe shaft 13 to the center of the handle 23, and the crank 17 may alsobe changed from one end to the other of the crank-shaft 13 12 16, andthus be operated by either hand,

while the other hand rests or is simply holdtwo) of air-nozzles3l,which, together with the tubes 32, extending from near said nozzlesdown into the vessel 39, form the atomizer proper.

33 is a lid swinging on the pivot 34. and serving to cover the aperture35, through which the fluid is admitted into the vessel 30.

36 is a guide secured to the top of the cylinder for steadying thepiston-rod 9 against the side strain of the cranks 12. The pistonrod istherefore extended beyond the crosshead and inserted in. said guide.

37 is a shield provided near back of and to the sides of theatomizing-point, so as to assist in spreading the spray by the partialvacuum produced in front of the shield. By the use of two or moreair-nozzles and tubes 32 the spraybecomes so wide that it covers a rowof potato-vines, and the operator may thus walk along as fast as he isable and keep turning the crank, about as indicated in Fig.

, 1, where 37 represents the end or cross-section of a row or hill ofpotatoes.

In operation the poison to be used is dissolved or mixed in water, whichis poured into the vessel 30, and after the apparatus is secured to theoperator, as shown, and the crank is turned the air-pump compresses anddrives the air out of the nozzles or spouts 31, thereby drawing thediluted poison or fluid up through the tubes 32 and blowing it into amist or fine spray, which will suffice to GXi 6lminate bugs and otherinsects of most any description on vegetation, animals, poultry, (36C.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is'

1. An insect-exterminator, comprising a double-acting han d-pu mpoperated by a crank and adapted to be secured upon the body of theoperator, a hose or flexible tube extending therefrom and an atomizersecured to the end of said hose, said atomizer having two or moreatomizing-point-s, so as to enlarge the spray, substantially as setforth.

2. In an insect-exterminator, the combination with the board 5 and meansfor securing same upon the breast or front side of a person, adouble-acting air pump secured to said board and having an extensiblehand-crank by which it is operated, and an atomizer attached by a hoseto said pump so as to receive compressed air from it, substantially asand for the purpose set forth.

3. In an insect-exterminator, the combination with the board 5 and meansfor securing same upon the breast or front side of a person, adouble-acting air-pump secured to said board and having an extensiblehand-crank by which it is operated, and an atomizer attached by a hoseto said pump so as to receive compressed air from it, said hand-crankbeing changeable to either side of the pump so as to be used by eitherhand, substantially as and for the purpose set forth.

4. In an insect-extcrminator, the combination with the board 5 and meansfor securin g same upon the breast or front side of a person, adouble-acting air-pump secured to said board and having an extensiblehand-crank by which it is operated, and an atomizer at tached by a hoseto said pump so as to receive compressed air from it; and an air-chamberfor equalizing the air-pressure and the spray produced by it,substantially as and for the purpose set forth.

5. lhe combination with a hand-operated 2tl1-pll111p, and an atomizeroperatively connected therewith, of means for securing the pump upon thebody of the operator, said means consisting mainly of a board or plateadapted to be placed upon the operators breast or front, and to whichthe pump is secured; another plate going on the back of the operator;shoulder-straps connecting the two platesin a suspending manner and theside straps 3, connecting the two boards together, substantially as andfor the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
